A variety of dietary choices are marketed to enhance glycogen recovery after physical activity, with recommendations regarding timing, dose and nutritional composition to facilitate glycogen recovery.
Eleven cyclists completed two trials including a 90 minute fasted ride followed by a four hour recovery period, followed by a 20km time trial. Immediately after the 90min ride and at two hours post ride the athletes were provided with equal macronutrient quantity of sports supplements of fast food.
Results showed no difference in blood glucose and insulin responses, nor was there any difference in glycogen recovery between sports supplements and fast food.
Some will take this study as justification for their post training/racing fast food binge. I would suggest that it is evidence of the misinformation and/or brilliant marketing that exists in the sports supplement world.
Perhaps a nail in the coffin of some well branded and marketed companies, though no doubt the aforementioned companies will do their best to ignore and/or discredit this research and other similar pieces of literature.
I would love to see the study repeated and compared to using organic/ethical real food. I hypothesise that the result would be quite different. But, perhaps not.
Food for thought.
